In idiopathic urethral strictures, bulbar urethra was the most common site in 61.76% of the patients followed by membranous urethra and penile urethra in 14.7% and 20.55% of patients respectively.
Bulbar urethra is the most common site of urethral stricture found in the 62% of the patients followed by the membranous urethra in 18% of the patients.
All patients in our series underwent transperineal repair with gracilis muscle interposition flaps for fistula ranging from 2-4 cm in length located between the bladder neck and the membranous urethra. The gracilis muscle was selected because it is far from previous radiation fields, has excellent vascularity, and is easily mobilized with minimal donor site morbidity.

A repeat cystourethrogram five weeks after urinary catheter insertion showed a small residual collection in the posterior membranous urethra. A subsequent third cystourethrogram six weeks later demonstrated complete resolution of the urethral leak, and the urinary catheter was removed.
We thank the authors for the beautiful contribution about the magnetic resonance imaging findings about the stretched length of the membranous urethra during radical retropubic prostatectomy (RRP) and its importance on postoperative continence.
Their study is based on the relationship between the length of the membranous urethra preoperatively and its positive impact on continence.
Our study suggests that not only the length of the membranous urethra, but also the preservation of its integrity might be important for continence.
